With the acquisition of the GYRO IPT (ETC) at the Canadian Forces School of Aeromedical Training (CFSAT), a further evaluation was completed on the helicopter configuration of the device and how the disorientation profiles specific to the helicopter might be implemented into existing undergraduate pilot training syllabus. The GYRO IPT is the most recent version of the GYRO-1 series of flight simulators. It features upgrades on the pitch and roll motion capability and options for data acquisition and medical monitoring. The major advantage of the device is its interactive closed-loop (pilot-in-the-loop) feature that forces the trainee to relate any demonstration to actual flight situations. In summary, the motion capability of the GYRO-IPT is able to elicit the type of vestibular illusions that are related to the inadequacy of the semicircular canals system (incapable of detecting constant velocity motion). Due to the limited pitch (+ or - 15 degrees) and roll (+ or - 30 degrees) capability and the lack of planetary rotation, otolith-medidated illusions cannot be demonstrated by the GYRO-IPT. The device reasonably deonstrates most of the visual illusion profiles such as leans, autokinesis, distance and depth perception, and false horizon. Improvements in the demonstration of nystagmus leading to loss of visual acuity, and reducing the size of the instrument display console are required to enhance some these demonstrations. TRUNCATED
